The impact of different biochemicals present in the genotypes/varieties of green gram on the life cycle and development of pulse beetle revealed that total protein, free amino acid, total soluble sugar, total phenols, tannin and flavonoid content had positive correlation in respect to resistance against bruchid. Total protein, free amino acid and total soluble sugar was found to be significantly higher in seeds of ML-1268, ML-1256 and KM-10-1040 than the rest genotypes or varieties of green gram. While, the same biochemicals were found to be significantly lower in seeds of COGG-912, KM-10-1039 and GM-08-09. Also, total protein, free amino acid and total soluble sugar content of seeds had highly significant and negative correlation with incubation period, larval-pupal period and total developmental of C. maculatus. On the other hand, total phenol, tannin and flavonoid were found significantly higher in GM-08-09 and COCG-912 and significantly minimum concentration was observed in against ML-1268 and ML-1256. They showed highly significant and positive correlation with incubation period, larval-pupal period and total developmental period. These antinutritional factors reflected higher resistance to pulse beetle.
